$ gem install rails breaks with a Zlib::DataError on actionpack, however
$ gem install rails -v 3.0.4 Works fine...?

    Please ensure you're using latest version of RubyGems, then try the same
    command adding --debug --verbose options and include the full output of that
    and gem env command.

    This could be due a corrupt downloaded file.

    Please try removing the cache directory (which you can see in "gem
    env" as I mentioned before under GEM PATHS)

    rm -rf path/to/cache

    The cache is inside the GEM PATH showed by "gem env"

    And try gem installation again.

    Thanks for the reply Luis

    I don't think it is a corrupt download as I am using rvm and the first thing I tried was switching ruby interpreters and gemsets, getting the same result for all.

    I did rm the directory anyway, with the same result.

    RVM symlinks cache directory along ruby interpreters

    Are you sure you removed the cache directory properly? What version of
    zlib is installed in your system?

    I have the latest zlib (Ubuntu version I suppose).

    I went so far as to completely remove rvm from my system and reinstall. I then installed ruby the normal way, and once linking against a downloaded zlib 1.2.5 (as per http://rvm.beginrescueend.com/packages/zlib/ ). None of this works.

    I was convinced this was a zlib error for hours, but everything else is working perfectly, including installing rails 3.0.4 . The only gem which refuses to install seems to be actionpack 3.0.5

    I have now tried manually downloading actionpack-3.0.5.gem from rubygems.org, and extracting it with fileroller.

    When opened, metadata.tar.gz opens fine, but trying to open data.tar.gz gives an unrecoverable error.

    I was able to manually download actionpack-3.0.5.gem, extract it and
    no failures.

    The file I downloaded weight 344 KB (352.256 bytes), perhaps your
    download is corrupt?

    The MD5 of my file is af25980a393ab111f9fcef3d65f73c89

    Well, I have no idea how, but actionpack downloads incorrectly on my local computer - and I get the wrong md5 on my local machine. However when I tried from my linode, the file downloaded fine, and the md5 is the same as yours.

    I suppose there could be some weird caching done by my ISP or something, but this is infuriating.

    Thanks so much for your patience and time Luis, you are awesome!

    Can you try the following?

    Try wget from http://production.s3.rubygems.org/gems/actionpack-3.0.5.gem

    That will skip Amazon CloudFront CDN which is being used in production and download directly from S3.

    If that works, it could be incorrect fetch from CloudFront to your closest point of delivery.

    Hope that helps.

    Going straight to the s3 server fetched the correct gem.

    I then changed to a different ruby, blatted all cached gems, and tried again, and, as if by magic, it worked fine... I reckon there was a broken gem cached somewhere, I just have no idea where.

    Thanks again for being awesome Luis
